BACKGROUND: While numerous studies evaluated dietary supplement use during the acute phases of the COVID-19 pandemic, evidence regarding health behavioral changes remains scarce, particularly in the Middle East. This study provides a comprehensive evaluation of self-reported changes in dietary supplement consumption patterns before and years after the pandemic in Jordan, in a region where evidence on post-pandemic supplement use is limited.
METHODS: A cross-sectional study was conducted in Jordan (from June to August 2025) among 427 participants, with pre-pandemic dietary supplement use assessed retrospectively through participant self-report. Wilcoxon signed-rank test and McNemar's test were used for paired analyses. Multivariable ordinal logistic regression was applied to identify predictors of changes in use.
RESULTS: Significant increases in the use of most dietary supplements were observed in the post-pandemic era (q < 0.05), with the exception of herbal supplements. Nearly half of the participants (49.2%) reported a sustained increase in dietary supplement use. Daily consumption rose sharply from 6.6% pre-pandemic to 31.4%, while non-use declined from 16.2% to 11.0% (p < 0.001). The perceived importance of supplements for ongoing health maintenance surged, with "very important" responses rising from 17.3% to 59.5% (p < 0.001). Heightened health awareness was the most frequently reported reason for maintaining or increasing intake (71.0%). Multivariable ordinal logistic regression showed that baseline pre-pandemic supplement-use frequency, recruitment mode and COVID-19 infection severity were significantly associated with changes in supplement consumption.
CONCLUSION: Changes in dietary supplement use in Jordan were observed after the pandemic, including a shift toward frequent and daily consumption. These findings suggest that changes in supplement-use behaviors remained evident in the post-pandemic period. The growing perceived value of dietary supplements underscores need for evidence-based public health guidance to promote safe and rational supplement use in the post-pandemic era.
